The LNER Encyclopedia

Evening all, just a quick one as I'm looking to expand my model collection by changing names and numbers, would anyone have any colour photos of A4's pre nationalisation, preferably of the first four in garter blue, but any coloured photos of any loco would help.
Cheers

If you prefer books, 'The Big Four in Colour', 'LNER Locomotives in Colour', are worth a look.
